Polyvinyl alcohol ( CHINA PVA )
1. Polyvinyl alcohol PVA Performace
Polyvinyl alcohol (abbreviated as PVA) also can be called PVOH. It is a kind of heavy polymer, produced by polymerization and alcoholysis of vinyl acetate. PVA is white or light yellow floccus, granular or powdery in appearance. Its molecular formula is[CH2CHOH]n,and the molecular formula for some of the PVA is -[CH2CHOH]n-[CH2CHOOCCH3]m-. PVA is non-toxic, insipid and harmless. It is water-soluble and the solvent provide good viscosity and film building.
